COMLEX-USA LEVEL 3 CDM - RESPONSE STRATEGY

YEAR 4 / PGY-1 | PAGE 71C - CASE PARTS -> RESPONSE LIMIT -> SPECIFIC ANSWER -> COMMIT -> NEXT PART

C. CURRENT CDM MECHANICS - DATE + FORMAT MATTER

Feature	Official mechanic	Preparation implication
Testing on/before Dec 19, 2026	Approximately 26 CDM cases within the current two-day Level 3 examination.	Practice current section structure and 26-case endurance.
Effective Jan 13, 2027	16 CDM cases within the new one-day Level 3 examination.	Practice one-day pacing; blueprint stays unchanged.
Case progression	Usually 2-4 questions/parts; earlier scenario text remains visible, but submitted answers cannot be changed.	Commit only after checking the response limit and wording.
Extended multiple choice	One or more correct choices may be required; exceeding the stated response limit can lose credit.	Select the smallest complete set.
Short answer	One specific response per box; 100-character limit per box in the current tutorial.	Use a precise diagnosis, exam step, study or treatment - not an essay.

DEEP EXPLANATION	WHY STUDENTS MISS IT	EASIEST CLUE
Extended-multiple-choice and short-answer items can specify how many responses are allowed. Exceeding the limit or combining multiple responses in one short-answer box can cost credit.	Clinicians are trained to think broadly, so learners may list every plausible test or treatment instead of the key decision set.	Count allowed responses before answering; use the smallest complete set.
